| Abstract | Dye sensitized solar cells (DSCs) modules are an emergent photovoltaic technology but still present some weaknesses in terms of long-term stability: sealing is presently the Achilles' heel of DSCs, which is currently preventing their commercialization. Thermoplastic sealants are normally used to bond the two glass substrates of a DSC. However, these thermoplastic sealants, such as Surlyn®, are permeable towards ambient water vapor, UV sensitive, and they cannot be used above 60 °C. Laser assisted glass-frit sealing is a very interesting alternative sealing technique as it has been demonstrated on microelectromechanical systems assembly. For these applications, the laser is shot around the sealing perimeter several times in a loop pattern. Nevertheless, for sealing large areas without heating the samples, this method cannot be applied since the laser loop takes more than 1 s, which is too long for an effective low-temperature glass-frit sealing. At present, work is described a laser assisted sealing techni... |
